Embodiment 1

[0039] The accompanying drawing shows an embodiment of the present invention. It can be seen from the accompanying drawings that the present invention relates to an anti-corrosion and waterproof end sealing device for the anchorage end of a bridge stay cable, comprising a bridge stay cable 1 and a stay cable anchor end conduit 2 and an anti-corrosion and waterproof end-seal device 3 at the anchoring end, and the anti-corrosion and waterproof end-sealing device 3 at the anchoring end is installed between the bridge stay cable 1 and the cable-stay anchor conduit 2, and the feature is that the anti-corrosion and waterproof end seal at the anchoring end Device 3 is an air-belt end-sealing device. The air-belt end-sealing device is inflated by a gas-inflated belt and then adheres closely to the outer surface of the bridge stay cable and the inner wall of the anchor end conduit of the stay cable to form a waterproof and anti-corrosion end seal device. A protective cover 5 is also set...

Embodiment 2

[0051] The basic principle of the second embodiment is the same as that of the first embodiment, except that the structure of the inflatable airbag belt is different. It is a kind of anti-corrosion and waterproof end sealing device for the anchorage end of the bridge stay cable, including the bridge stay cable 201, the stay cable anchor The end conduit 202 and the anchoring end anticorrosion and waterproof end sealing device 203, and the anchoring end anticorrosion and waterproof end sealing device 203 is installed between the bridge stay cable 201 and the cable stay cable anchor end conduit 202, which is characterized in that the anchoring end anticorrosion The waterproof end-sealing device 203 is an air-belt end-sealing device. The air-belt end-sealing device is inflated by the gas inflatable belt and then adheres to the outer surface of the bridge stay cable and the inner wall of the anchor end conduit of the cable stay to form a waterproof and anti-corrosion end seal device....

Embodiment 3

[0055] The basic principle of the third embodiment is the same as that of the second embodiment, except that the structure of the inflatable airbag belt is different. It is a kind of anti-corrosion and waterproof end sealing device for the anchorage end of the bridge stay cable, including the bridge stay cable, the anchor end of the stay cable The anti-corrosion and waterproof end-sealing device for the conduit and the anchoring end, and the anti-corrosion and waterproof end-sealing device for the anchoring end is installed between the stay cable of the bridge and the anchor end conduit of the cable-stayed cable. The belt-type end-sealing device and the air-belt-type end-sealing device are inflated by the gas inflatable belt and then adhered to the outer surface of the bridge stay cable and the inner wall of the anchor end conduit of the stay cable to form a waterproof and anti-corrosion end seal device.

[0056] The gas inflatable belt is an inflatable airbag belt. When the ma...

Abstract

The invention relates to an anticorrosion and waterproof end sealing method for a bridge stay cable anchoring end. An air elastic isolating mode is utilized to realize the anticorrosion and waterproof end sealing of the bridge stay cable anchoring end; an annular air bag type isolating ring formed by taking an air bag as a main body is arranged between the outer surface of a bridge stay cable and the inner wall of the pipe at the bridge stay cable anchoring end; and an air bag isolating end seal is formed between the outer surface of the bridge stay cable and the inner wall of the pipe at the bridge stay cable anchoring end by the annular air bag type isolating ring at the bridge stay cable anchoring end, so that the anticorrosion and waterproof effects of the bridge stay cable anchoring end can be achieved. According to the invention, the big space between the pipe at the bridge stay cable anchoring end and the stay cable is filled with the air bag with certain elasticity, air bag type plugging is formed, the corrugated small space of the air bag is filled with an adhesive rubber tape, and a fixing function is utilized to achieve an excellent plugging effect at a pipe opening.

Description

technical field [0001] The present invention relates to a protection method and structure for components of a bridge, in particular to a method and device for sealing an anti-corrosion and waterproof end of a cable-stayed anchorage end of a bridge, which is mainly used for the end-sealing of the anchorage end of a cable-stayed cable to prevent bridge A stay cable in a stay cable casing is corroded by water or other sundries, and belongs to the technical field of bridge component manufacture. Background technique [0002] The cable-stayed cable system of modern long-span bridges is the main load-bearing structure of cable-stayed bridges. Due to the special use environment and conditions of the stay cables, the corrosion phenomenon is relatively serious. According to the actual inspection of the use and accident status of the stay cable, the protection failure of the stay cable system mostly occurs at the end, because this part is inconvenient to inspect and maintain due to s...
